Specification of Letters Patent.

To all whom 'it may Concern:

Be it known that I, WILLIAM S. WHITE, a citizen of the United States, residing at Tracy City, in the county of Grundy and State of Tennessee, have invented new and useful lmprovements in Cultivators, of which the following is a specification.

This invention relates to cultivators, and it has particular reference to a disk cultivator of the sulky type.

The invention has for its obj ect to produce a simple and efiicient implement of this class which may be readily drawn bya single draft animal.

A further object of the invention is to produce a simple and eliicient disk cultivator wherein the disks may be readily interchanged from right to left so as to move the dirt toward or from the plants, as may be required.

A further object of the invention is to simplify and improve the general const ruction, arrangement and combination of parts entering into the construction of the device.

W ith these and other ends in view which will readily appear as the nature of the in vention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

ln the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifica.- tions within the scope of the claims may be resorted to when desired.

In the drawings, Figure 1 is a top plan view vof a cultivator constructed in accordance with the invention, the seat and seat support having been broken away. Fig. 2 is a view partly in side elevation and partly in longitudinal section taken on the line 2-2 in Fig. 1. Fig. 3 is a vertical transverse sectional view taken on the line 3--3 in Fig. 1. Fig. il is a longitudinal sectional view of one of the axles. Fig. 5 is a sectional view of one of the journal boxes. Fig. 6 is a perspective detail View ofy one of the bearing sleeves. Fig. 7 is a side elevation of one of the disks. Fig. 8 is a side view of one of the washers. Fig. 9 is a side view of a spading disk sometimes used in connection with the device.

Corresponding parts in the several figures are denoted by like characters of reference.

The frame of the machine includes a pair of thills or shafts 15 which are connected together and spaced apart by means of cross bars 16, 17 and 18 which have been shown as consisting of metallic angle bars. rlhe intermediate cross bar 17 and the rear cross bar 18 support arches 19, 20 which are connected together by longitudinally disposed braces 21 supporting the drivers seat 22. A draft element, such as a swingletree 23, is mounted on the front cross bar 16.

Tool carrying standards S, S', four in number, are carried by the front and intermediate cross bars 16, 17, each of said standards being composed of a substantially triangular frame, one side of which, 24, is bolted or otherwise secured on the end faces of the cross bars 16, 17; another side member 25 which is integral with the side member 24 is bent downwardly and rearwardly with respect to the side member 24; the third side member 26 constitutes a brace which is terminally connected with the side Gil members 24 and 25 at the upper forward end of the former and adjacent to the lower under the middle portion of the frame, are

connected together' by across piece 27 to prevent wabbling and vibration when the machine is in operation.

Each of the standards supports a iournal box. B consisting of a block or casting having a transverse bore 28 and an aperture or socket 29, said socket being adapted to receive the shank 25 at the lower extremity of the member 25 of the'standard on which it is mounted and on which it is secured by means of a cotter pin 30. The block B is provided with threaded apertures 31. 32 communicating with the bore 28. one of said apertures being for the reception of a set screw 33 while the other receives an oil cup 34 having a threaded shank or stem 35 which also extends through an aperture 36 in a bearing sleeve 37 with which the box is provided.

For the equipment of the improved cul-
